10 tion, such as will enable others skilled in'theart to which it appertains to make and use the same My invention relates to apparatus for examining submerged bodies; the object of my invention is to provide in such an ap aratus means for reflecting a light downwar on the body to be examined, and to provide means for protecting the interior of the apparatus from the water; a further object is to rovide an apparatus with a sight tube ma e in sections, so that it may be adjusted to varying depths; and, my invention consists of the construction, combination and arrangement of arts, as herein illustrated, described and clalmed. In the accompanying drawings,

forming part of this application, I have illustrated one form of embodiment of my invention, in which drawing similar reference characters designate corresponding parts, 'and in which: the figure is a vertical section,

partly in elevation.

Referring to the drawings, 1 1 designate sections of tubular material movably secured together as by the sleeve 2. By this construction, the tube formed by the sections 11 may be lengthened or shortened to suit varying conditions. A removable eye-piece 3 is disposed on the upper end of the upper section 1 of the tube. A i'rusto conical 40 drum 4 is secured to the lower end of the lowermost tube section 1, as by means of the rivets 5, so as to form a waterti ht joint. Carried by the drum 4 adjacent its lower end on its inside surface, is a gasket 6, against the lower edge of which is dis osed a sheet 7 of transparent material, whic is maintained in position a ainst the gasket 6 as by means of a ring 8 of cement or similar material, so that a Watertight joint is formed. To protect the'transparent sheet 7, suitable guards 9 comprising owed metallic bands secured at their opposite ends to the drum and at their intersection one to another are provided. Carried on the inner surface of the drum 4, intermediate of its ends, are brackets 10, on which is disposed a mirror 11,

adapted to deflect light downward, and pro-. videdwith a central opening 12,

Disposed through the tube sections 1 is an electric cable 13, in connection with a suitable source of power, and having on the lower ends of its wires incandescent electric lamps 14, which extend below the surface of the reflecting memberll. The Wires to the lamps 14 are passed through the reflecting member 11, and'preferably pass through the brackets 10, so that they are kept from swaying. The light from the lam s 14 is reflected downward, so that the objects beneath the a par-atus may be surveyed through the tube sectionsnlthrough the opening 12', and through the glass 7.

Secured to the outer surface of the drum 4, adjacent its lower end, is an eye 15, ada ted to be engaged by a hook on a common orm of block 16, through which block is disposed a flexible member 17, by means of which the apparatus may be raised and: lowv ered, and by means of which the apparatus may be suspended so that it may be easily adjusted.

Having thus fully described my invention, what I claim as new,and desire to secure by Letters Patent is 1. In a device of the character described, the combination comprising, tube sections, a sleeve adapted to telescopically receive said sections, a frusto-conica drum rigidly secured to one of said tube sections and an eyepiece removably carried by the other of said tube sections, brackets attached to the inner face of said frusto-conical section, a horizontally mounted mirror carried by said brackets and adapted to reflect light downwardly, electric lights carried by said brackets and mounted directly beneath said mirror and a transparent closure for the lower end of the drum.

2. In a device of the character described, the combination comprising, tube sections, a sleeve adapted to telescopically receive said sections, a frusto-conical drum ri idly secured to one of said tube sections an an eye.- piece removably carried by the other of said, tube sections, brackets attached to the inner face of said frusto-conical section, a horizontally mounted mirror carried by said brackets and adapted to reflect light downwardly, electric lights carried bysaid brackets and mounted directly beneath said mirror, a trans; -.ren t closure for the lower end of the drum, and a guard for said closure.

transparent closure for the lower-end of that drum and a guard for said closure said guard comprising bowed bands secured at thenop- 15 posite ends to the drum.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
